Yes, it is! Just make sure that your contest isn't breaking any laws where you live, and that it's not in violation of the regulations most social media networks have in place.

Of course, we recommend embedding your contest or sweepstakes on your website, or hosting it as a landing page -- and then promoting the link on your social networks -- so you don't have to worry about breaking rules individual platforms' regulations.

Current regulations for the most popular platforms are listed below:

Facebook Promotion Guidelines

Twitter Promotion Guidelines

Businesses, organizations, and even some creative individuals have hosted contests and sweepstakes through their Twitter profile. Contests and sweepstakes on Twitter may offer prizes for tweeting a particular update, for following a particular user, or for posting updates with a specific hashtag. If you’ve been thinking about hosting a contest using your Twitter profile, here are some simple guidelines to follow to ensure your contest doesn't ask anyone to violate any of Twitter's rules or guidelines:

1. Discourage the creation of multiple accounts.

If users make lots of accounts in order to enter a contest more than once, they’re liable to get all of their accounts suspended. Please be sure to include a rule stating that anyone found to use multiple accounts to enter will be ineligible.

2. Discourage posting the same Tweet repeatedly.

Posting duplicate, or near duplicate, updates or links is a violation of the Twitter Rules and jeopardizes search quality. Please don’t set rules to encourage lots of duplicate updates (like saying, “whoever retweets this the most wins”). Your contest or sweepstakes could cause users to be automatically filtered out of Twitter search. Plus, instead of their followers seeing your cool contest or sweepstakes, their followers might start getting annoyed by your contest. You might want to set a clear contest rule stating that multiple entries in a single day will not be accepted.

3. Ask users to include an @reply to you in their update so you can see all the entries.

When it comes to picking a winner, you’ll want to see all the contestants. If the updates include @username mention to you, you’ll be able to see all the updates in your Mentions timeline. Just doing a public search may not show every single update, and some contestants may be filtered from search for quality.

4. Encourage the use of topics relevant to the contest.

You might decide to have users include relevant hashtag topics along with the updates (like #contest or #yourcompanyname). Keep in mind that hashtag topics need to be relevant to the update; encouraging users to add your hashtag to totally unrelated updates might cause them to violate the Twitter Rules.

5. Follow The Twitter Rules.

While these guidelines should help keep your contest entrants in good standing, please make sure you also review both the Twitter Rules and our search best practices before starting your contest.
